The ST-VOX1 Voice Operated Relay can be actuated by an unbalanced mic or line level source. It is primarily used in intercom and talkback applications where a fast contact release time (adjustable 70 to 260 ms) is desired. In applications where longer release times are desired we suggest the use of ST-ACR Series Audio Controlled…
Stereo Unbalanced to Balanced Conversion with Adjustable Gain
The ST-UBA2 Two Channel Unbalanced to Balanced Amplifier is used in applications where unbalanced consumer level signals must be converted for operation in a professional +4dBu environment.
The 10 kOhm unbalanced Left and Right inputs are designed to accept signals from -20 dBV to -10 dBV. Multi-turn gain trimmers and Dual-LED VU meters are provided for each channel allowing the installer to precisely and independently set the gain for the Left and Right outputs. A summed mono output is also available for driving monitor or subwoofer amplifiers. All three outputs are balanced 150 Ohm. The adjustable gain range is 2 dB to 22dB.
Featuring the audio clarity, low-noise, low-distortion and excellent crosstalk performance typical of RDL STICK-ON® modules the ST-UBA2 can be installed where ever you might need it.
